I have tried a lot of diets and my personal experience is that if I dont have someone babysitting me or looking over my shoulder then I tend to be a slacker when it comes to dieting and exercise. I waited almost 6 mos but I joined LAWL during my COD's open house and got 58 weeks of weight loss for $199. I know that doesnt include the maintenance, but I'll cross that bridge when I get there. So you may keep an open ear for a promotion or sale.
But if you feel that doing it online could work for you then it may be cheaper that way. When it comes down to it, only you know You!
